mixing signed and unsigned types in comparison can end up having
unintended results. for example:
if (-1 < 1U)
printf("true\n");
else
printf("false\n");
previously we silenced these warnings, instead just fix them properly
via necessary casting, and in cases where the value cannot be negative
(e.g width/height members) make them unsigned.

* includes are sorted alphabetically
* their grouping and layout is the following:
- nsxiv.h will be the first include
- followed by any internal headers (e.g "commands.h" "config.h")
- followed by system headers (<stdlib.h> etc)
- followed by third party headers (X.h libwebp etc)
* also add `llvm-include-order` check to clang-tidy so that it can catch
unsorted includes during CI.
cppcheck warns about passing a plain NULL to construct_argv()
main.c:254:36: portability: Passing NULL after the last typed argument to a variadic function leads to undefined behaviour. [varFuncNullUB]
fidx, fcnt, w, h, z, NULL);
in our case, POSIX mandates `NULL` to be defined as `(void *)0` rather
than a plain `0` [0]. and void pointers are required to have the same
representation and size as char pointers [1]. so this is not an issue we
need to worry about.

- apt-get is slow, takes up ~1m40s just to install deps, fix it by not
using it. instead use alpine linux for codeberg ci, which brings build
time down to 25s.
- And since alpine uses musl, it's probably a good idea to use it on our
ci since it might catch us using any glibc extensions. The github ci
can keep using ubuntu.
- remove duplication of CFLAGS by having it on a separate file instead.
- remove pull_request from github ci since we no longer accept PRs
there.
